Plasma vs LCD TVs

My husband is a big nerd for electronics. Today he was showing me an article about LCD TVs outselling plasma, even though plasma has been considered 'the best' for ages. I'm not really sure what to think of that. We have an LCD TV and it is pretty darn awesome. My in-laws have a plasma TV, I believe, and they are frequently having problems with it. To me, it seems like LCD is the way to go.
